APPARATUS FOR FEEDING ARTICLES INTO OVENS.

Specification of Letters Patent.

Patented April 24, 1906.

To ml," whom it may concern.-

Be it known that I, WILLIAM STENDER, a citizen of the United States, residing at Streator, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Apparatus for Feeding Articles into Ovens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements for feeding bottles and other articles into annealing-ovens, furnaces, or the like.

The object of the invention is to provide an apparatus of this character by means of which bottles or other articles may be expeditiously and automatically fed into an annealing-oven or similar place.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view through an annealing-oven or furnace with my im proved feeding means applied thereto. Fig. 2 is a front end elevation of the same with parts in section. Fig. 3 is a horizontal sectional view taken on the plane indicated by the line 3 3 in Fig. 1. Fig. 4 is a detail vertical section, and Fig. 5 is a detail sectional view taken on the plane indicated by the line 5 5 in Fig. 1 and looking in the direction of the arrow.

Referring to the drawings by numerals, 1 denotes a leer or annealing-oven in which bottles or other articles of glass or the like may be annealed. This leer comprises a housing 2 of substantially rectangular form, in which is mounted a longitudinally-movable support or table 3. The latter, as shown, consists ofa plurality of endless cables, of wire or the like, arranged in parallel relation and passing over grooved drums 4, mounted transversely adjacent to the forward and rear ends of the housing. Suitable supporting rollers or drums 5 are arranged intermediate the drums 4 for the )urpose of supporting the upper stretches of the cables upon which the bottles or other articles are supported and by which they are conveyed from the forward end of the oven to its rear or discharge end. One end of the shaft 6 of the forward drum or wheel 2 projects through the side wall of the housing 2 and has upon its end a band-wheel or similar driving element 7. The oven may be heated in any desired manner but as shown a fireplace 8 is provided at one side of the forward end of the housing.

The forward end of the housing 2 is provided with a plurality of inlets or article-receiving ope'nin gs 9, adjacent to which my improved feeding apparatus is mounted. These openings 9 are arranged in the vertical front wall of the housing just above flooring or table 10, which is arranged horizontally and on a line with the moviit g table or conveyor formed by the tables 3. In the accompanying drawings I have shown four devices 11 for receiving and feeding the bottles or other articles, arranged in trarsverse alinement upon and beneath the stationary flooring or table 10. Since each of these devices 11 is similar in corstruction and operation, a.description of one will suflice for all. Each device comprises a substantially circular casirg 12, supported above the table 10 in flOLt of one of the openings 9 and having on its inner side an opening which ali'nes with said opening 9. Upon the top of the casing 12 is a funnel-shaped guide 13, ii to which the bottles are inserted when it is desired to feed them intothe oven. This funnel 13 has in its inner side a vertical slot 14, through which the neck of the bottle passes. Movable vertically through each casing 12 is a bottle or article receiver 15, which comprises a head 16 and a reciprocating rod 17. The latter proj ects through and slides in operings formed in the table 10 and in a trarsverse support 18, arranged beneath the table. The head 16 is adapted to receive the bottom of the bottle or other article, as clearly shown in Fig. 1 of the drawings. The rod 17 is formed with a longitudii.ally-extending recess or flattered portion 19, which is ada )ted to prevent it om rotating, and in sai rod above the recess 19 is a notch 20, the )urpose of which will be presently explained. The receiving device is adapted to be held normally in an elevated position, so that the head 16 is in the upper portion of the casing 12, and it is adapted to be depressed by the weight of the bottle orothor article placed upon it.

The receiver 15 is preferably elevated by a counterbalancing device which comprises a weighted lever 21, which is pivoted intermediate its ends at 22 upon a suitable hanger or bracket rovided upon the support 18. Said lever 21 has its forward end loosely connecta stationary,

IIO

ed, by means of a link 23, to the lower end of the rod 17, and upon its opposite or inner end is a weight or a series of weights 24. The

weight or weights 24 may be varied accord- 5 ing to the weight of the bottles or other articles to be fed into the oven. The bottles or other articles are adapted to be moved from the heads 16 of the receivers through the openings 19 and into the oven by means of a rotary feeding device 25. The latter is mounted directly beneath the forward portion of the table and, as shown, consists of a drum or roller 26, secured upon a transversely-extending shaft 27, which is mounted in suitable bearings and has one of its ends projecting through the side wall of the housing 2 and provided with a pinion 28, which meshes with a gear 29, secured upon the shaft 6. Upon the drum or shaft 26 are arranged pairs of radially-projecting parallel arms 30, which are adapted to pass through arallel longitudinally-extending slots 31, formed in the portion of the table 10 beneath the casings 12. The arms 30 of each pair are adapted to pass upon the opposite sides of one of the heads 16, so that when the shaft 27 is rotated said arms will move the bottles or other articles upon the heads 16 off of the latter, through the openings 9, and into the oven, V-shaped guides 31 being preferably provided upon. the inner portion of the table 10, as shown in Fig. 3 of the drawings. In order to hold the receivers 15 in their lowered positions while the arms 30 are moving the bottles or other articles from the heads 1-6, I provide means for locking said receivers against movement during this period. This means, as shown, consists in latch plates or blocks 32 under the table 10 and arranged between pairs of slots or openings 311 in the table 10. These latches are pivoted at one end, as shown at 33, and are formed at their opposite ends with angularly-arranged slots or openings 34. Said latches when swung to their full-line positions (shown in Fig. 5 of the drawings) are adapted to engage the notches 20, formed in the rods 17, and when swung to their dotted-line position (shown in said figure) are adapted to project across one of the arms 30. When in these dottedline positions, it will be seen that said arms 30 as the latter pass through the slots 31 will move the said latches to their fullline positions, in which they will engage the notches 20 in the rods 17 and hold the latter in their lowered position. Said rods are released after the bottles have been moved from the heads 16 by short pins 35, which are arranged at suitable points upon the drum or roller 26 and which are adapted to enter the angularly-disposed slots 34 in said latches when the latter are in their full-line position. (Shown in Fig. 5.) It will be seen that when 65 they are in this position and the pins 35 enter one of the slots 31 and to lie in the path of the slots 24 the latches will be swung to their dotted-line position to release the rods .17 and permit their counterbalancing devices to elevate them to receive other bottles. It will be seen that this feeding mechanism is automatic in its operation, the receivers being lowered by the weight of the bottles, then locked by the arms 30 as the latter move the bottles into the oven, and then released and restored to their normal positions by the pins 35 as the shaft 27 continues to rotate.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the principle or sacrificing any of the advantages of this invention.
